WICK-RAISER FOR CENTRAL-DRAFT LAMPS.

SPECIFICATION forming part of Letters Patent No. 409,910, dated August27, 1889.

Application filed May 13, 1889- Serial No. 310,553- (No model.)

To all whom it may concern.-

Be it known that I, EDsON L. BRYANT, of Ansonia, in the county of NewHaven and State of.Connecticut, have invented new Improvements inNick-Raisers for Central-Draft Lamps; and I do hereby declare thefollowing, when taken in connect-ion with accompanyin drawings, and theletters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of thisspecification, and represent, ii1

Figure 1,. a sectional view of the fount and burner, with a side view ofthe wicleadjuster; Fig. 2, a perspective viewof the wick-adjusterdetached; Fig. 3, a transverse section through the wick-tube on line a;00, showing top view of the wick-adjuster ring; Figs. land 5,modifications.

This invention relates to an improvement in wick-adjusters for thatclass of lamps in which the wick is of tubular shape arranged in thefount around a tube, open from below to admit air through the tube andwick to the flame at the top of the wick-tube, commonly calledcentral-draft lamps, and particularly .to that class of adjustingdevices in which a rod is arranged to work outside the burner and inconnection with the wick, and so that by lifting the rod to draw it fromthe fount the wick will be raised 01' pressed downward, and willcorrespondingly lower the wick, the object being a simple and effectiveconstruction; and it consists in the construction as hereinafterdescribed, and particularly recited in the claims.

A represents the fount, having a central opening B in the top, and overwhich opening the burner C is arranged in the usual manner.

D represents the wick, surrounding the central air-tube E, and so as toslide up and down thereon, as usual in this construction of lamps.

The wick-adjuster is made from a single piece of wir At the lower endthe wire is bent into ring shape F of slightly elliptical form, itsdiameter 011 the line a being somewhat less than the external diameterof the wick when arranged upon the central tube.

The longer diameter on the line b is greater than that of the diametera. From one side of the ring on the longer diameter the wire extends upto form the lifting-rod G. This is curved and so that its upper end maypass through an opening II in the burner above the neck, or through anyother convenient point, so that the outer end may form a handle I, bywhich the rodmay be raised or lowered. The wick is placed upon thecentral tube in the usual manner. Then the wick-adj uster is set inplace, the ring F passing over the wick, and so that its shorterdiameter will impinge closely upon the wick to grasp the wick betweenthe opposite points on the shorter diameter and the inner tube withsuflicient force that when the ring is raised or lowered the wick willmove with it. The wick and wick-adjuster are thus arranged before theburneris applied. Then the burner is set in place, first passing thehole H over the outer end or handle I of the rod G, and when the burneris in place, as seen in Fig. 1, this opening through the burner servesas a guide for the rod. The rod G is curved, as shown, and so that as itrises it swings outward through its opening and away from the burner, asseen in broken lines, Fig. 1. In this swinging movement of the rod thelifting-ring- F turns upon the wick, its opposite hearings on the wickserving as pivots for such turning, so that the ring will assumedifferent planes according to the position of the ring with relation tothe support for the red, and as seen in broken lines, Fig. 1. The longerdiameter of the ring D permits this play of the ring on the wick.

I have thus far described the ring as'made of elliptical shape, so as toproduce the longer 0 diameter in the plane of the lifting-rod, in orderthat the points at the shorter diameter may bear directly upon the wickand without forcible contact on the longer diameter; but the same resultwill be attained by making 5 the ring of a complete circle and of adiameter corresponding to the longer diameter required for thewick-raising ring, and then i11- denting it at opposite points, asrepresented at c, Fig. 4, so as to short-en the diameter bezoo tweenthose points to produce the beforementioned bearing upon the wick; orthe shortening of the diameter may be produced, as seen in Fig. 5, bymaking a cut into the ring upon the inside at opposite points, so as toturn a tongue, as f, inward, to take its bearing upon the ring. Thisalso produces substantially the elliptical internal shape of the mug.

' By this construction the wick-adjuster may be made complete from asingle wire without joints or connecting devices. It is removableentirely from the fount with the wick, yet when in place is supportedand guided for proper operation.

It will be understood that while the adjuster is adapted to be made (andI prefer to make it) from a single piece of wire because of itscheapness and durability, it may be made from other metal. In any casethere is substantially the same simplicity and cheapness of constructionwith convenience in operation, and the lifter as it rises moves awayfrom the burner, so as to avoid the heat of the burner in handling.

While I prefer the opening through the burner, as I have described, asthe guide for the rod, itwill be evident that it may pass through anopening prepared for it in the fount, as indicated in broken lines, Fig.1.

I claim- 1. The herein-described wick-adjuster for central-draft lamps,consisting of a ring to surround the wick, the diameter of the ring inone direction somewhat less than the eX- ternal diameter of the wick asit stands upon the tube, and the diameter of the ring at right angles tothe said less diameter somewhat greater than the said diameter of thewick, and the ring constructed with a curved rod in the plane of itslonger diameter, extending upward and through a suitable guide outsidethe burner, substantially as described.

2. A wick-adjuster for central-draft lamps, consisting of the ring F,somewhat less in diameter in one direction than the external diameter ofthe wick as it stands upon the tube, and the diameter of the ring atright angles to the less diameter somewhat greater than the saiddiameter of the wick, and having a rod G extending therefrom in theplane of the longer diameter, the said rod and ring made from a singlepiece of wire, substantially as described.
